APPLICATIONS
Achieve acoustical privacy in open and partitioned office areas by installing Atlas Sound’s self-
contained, audio masking system — The Masker. Compact assembly adds low-level sound into
environment to obscure ambient noise, achieving conversational privacy in designated areas.
Easy-to-install system may be used in general application to increase privacy and/or productivi-
ty in individual cubical and work areas by “blocking out” surrounding conversation. It is also
used in individual office areas, common waiting areas, and professional offices where confiden-
tial conversations occur. The equalized masking sound lowers intelligibility and “masks” disrup-
tive outside sounds.
GENERAL DESCRIPTION

includes a built-in power supply, digital pink-noise generator, 2-watt amplifier, 4" loudspeaker
and selection of optional installation and performance enhancements. Compact assembly is
housed within a 6" metal cube enclosure with one point suspension to allow 360° positioning in
ceiling plenums.
Easy-to-operate control panel features on/off power switch, screwdriver-adjust master SPL
level control, knob adjust attenuator (1
1
⁄2 dB per step), and two screwdriver-adjust low-pass fil-
ters. For installation convenience, the sound out-put curve of The Masker is pre-set at the fac-
tory to meet most masking applications (see Fig. 1).

request. The 117VAC versions are standard with transformer, IC electronic regulator, replace-
able fuse and grounded plug or conduit connector for termination. The 16VAC version is
